Comparative analysis of the prevalence complications in the teeth preparation for different types of orthopedic structures using classical and minimally invasive protocols

Annotation. The research analyzes the prevalence of biological and technical complications in orthopedic rehabilitation of dental patients and comparative evaluation of classical and minimally invasive protocols of preparation for different types of orthopedic structures. Study goal - to make a comparative assessment of the prevalence and relative risks of biological and technical complications in the teeth preparation for different types of orthopedic structures using classical and mini-invasive protocols in prosthetic rehabilitation of dental patients. During the study 725 dental patients were comprehensive examined. The patients rehabilitation with the usage of different orthopedic structures types was evaluated, the average term of their functioning was studied and biological and technological complications in orthopedic treatment were registered. Relative risk indicators of biological consequences of iatrogenic interventions in comparison with the vital teeth condition which not covered with orthopedic structures are calculated. The following statistical research methods were used: bootstrap variant of analysis using Duncan's criterion and Pearson's consistency criterion with Yates correction. It is established that minimally invasive design of orthopedic structures (partial ceramic and all-ceramic veneers) is characterized by a statistically lower level of relative risk of complications, including both biological and technical. So, the implementation of minimally invasive protocols for the preparation of teeth for different types of orthopedic structures helps to reduce the relative risk of associated complications (mainly by reducing the risk of adverse effects), preserving more hard tissues of enamel and dentin compared to dentin and dentin. the magnitude of the risk of complications during the classical preparation protocols.
